The following equation is being multiplied by the lcd. complete the multiplication to eliminate the denominators
x+2/3x - 1/x-2 = x-3/3x

(3x)(x-2) [x+2/3x - 1/x-2] = (3x)(x-2) [x-3/3x]

the resulting equation is

x+2-1 = x-3

3x(x+-2) = x-3

(x-2)(x+2)-1 = (x-3)(x-2)

(x-2)(x+2)-3x=(x-2)(x-3)

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
